First, let's upgrade myro. Start python and enter the following commands and then restart

−

python:

−

>>> from myro import *

+

If you are using version 2.5.0 or later of the [[IPRE Fluke]] firmware (All new flukes have version 2.7.4 by default), then you need only Start Python and issue the commands:

−

>>> upgrade("myro")

+

−

>>> exit # or quit idle

+

−

+

−

If you are using version 2.5 or later of the [[IPRE Fluke]] firmware, then you need only Start Python and issue the commands:

+

>>> upgrade("fluke")

>>> upgrade("fluke")

−

=== Manual Fluke Upgrade - VERY OLD FLUKES only! ===

−

If you have an older version (version 2.4 or earlier) of the [[IPRE Fluke]] firmware, then you will need to directly connect to the Fluke with a serial cable, provide an external power supply, download the .hex file, and download and run the program . Note that you will only have to do the serial connection '''once''' with the older version, after which you can simply do (A) above.

If you have an older version (version 2.4 or earlier) of the [[IPRE Fluke]] firmware, then you will need to directly connect to the Fluke with a null-modem serial cable, provide an external power supply (a 9v battery will work), download the .hex file, and download and run the program . Note that you will only have to do the serial connection '''once''' with the older version, after which you can simply do the "over-the-air" upgrade procedure above.

Detailed Instructions for a serial cable firmware upgrade:

−

# Connect your Fluke via serial cable to the computer, and also hook up a power line to your Fluke.

# Connect your Fluke via serial cable to the computer. Your serial cable will need a "null-modem" adapter to swap the control and data lines correctly. Also hook up a power line to your Fluke. A standard 9 volt battery will provide enough voltage/current. (the +ve and -ve ends of the battery connecting to the 11th and 12th pins of the connector on the fluke board.)

# Download program found at http://myro.roboteducation.org/packages/lpc21isp-ipre-win.zip. Make sure to save program to desktop. (If you need to unzip, right click the downloaded folder and choose "Explore". You may need to 'open containing folder' & ''then'' "Explore".)

If your fluke is producing images like the one below, it's not a problem, you just need to give it more light!

Upgrading Your Fluke

If you are using version 2.5.0 or later of the IPRE Fluke firmware (All new flukes have version 2.7.4 by default), then you need only Start Python and issue the commands:

>>> upgrade("fluke")

Low Light Images
If your fluke is producing images like the one below, it's not a problem, you just need to give it more light!
What is happening is that some light is leaking through the back of the circuit board and the image sensor. The black spots you see are wires behind the image sensor chip. Take the fluke to a well lit environment (florescent lights in a classroom, or outdoors during the day) and enough light will come into the lens so that the light from the back won't register.
